An image pickup apparatus includes: an image pickup lens section; an image pickup device obtaining image pickup data on the basis of light detected; a microlens array section arranged on a focal plane of the image pickup lens section, and including a plurality of microlenses, each of the microlenses being provided corresponding to a plurality of image pickup pixels of the image pickup device; and a light-condensing section configured of a plurality of light-condensing elements, each of the light-condensing elements condensing light entering into each of the image pickup pixels of the image pickup device, wherein on the image pickup device, in a pixel region corresponding to each microlens, the pitch between the light-condensing elements is smaller than the pixel size, and in a boundary region between pixel regions corresponding to microlenses, respectively, the pitch between the light-condensing elements is larger than the pixel size.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The image pickup apparatus according to claim 1 , wherein in each pixel region corresponding to each of the microlenses, the center position of the light-condensing element coincides with the pixel center position of the image pickup pixel in a central region of each of the microlenses, and is gradually shifted from the pixel center position of the image pickup pixel with approach toward a peripheral region of each microlens.
3. The image pickup apparatus according to claim 1 , further comprising: an image processing section performing predetermined image processing on the image pickup data obtained by the image pickup device.
4. The image pickup apparatus according to claim 1 , wherein the image pickup apparatus includes: an image height correction section performing image height correction on the image pickup data obtained by the image pickup device so that an image size, in the predetermined direction, of an image formed on the image pickup device by each of the microlenses is equal to an integral multiple of a pixel size, in the predetermined direction, of the image pickup pixel.
6. The image pickup apparatus according to claim 5 , wherein in each pixel region corresponding to each of the microlenses, the center position of the light-condensing element coincides with the pixel center position of the image pickup pixel in a central region of each of the microlenses, and is gradually shifted from the pixel center position of the image pickup pixel with approach toward a peripheral region of each microlens.
7. The image pickup apparatus according to claim 5 , further comprising: an image processing section performing predetermined image processing on the image pickup data obtained by the image pickup device.
